Hot Rod per-cache configuration
Aside from being able to configure a Java Hot Rod client through a compact URI representation, Infinispan 11 brings some additional changes to remote cache configuration.
While remote caches did have some client-side configuration, this was never implemented cleanly, resorting to multiple overloaded variations on the getCache() method, for example to obtain a transactional cache, or enabling near-caching.
Infinispan 11 now allows specifying per-cache configuration both through the API and through the declarative properties file.
Let’s look at a few examples.
ConfigurationBuilder builder = new ConfigurationBuilder()
.uri("hotrod://127.0.0.1");
.remoteCache("closecache")
.nearCacheMode(NearCacheMode.INVALIDATED)
.nearCacheMaxEntries(10000)
.remoteCache("txcache")
.transactionMode(TransactionMode.NON_XA);
RemoteCacheManager manager = new RemoteCacheManager(builder.build());In the above code snippet, we enable near-caching for the cache closecache and we enable NON_XA transactions on the cache txcache.
The equivalent hotrod-client.properties file:
infinispan.client.hotrod.uri=hotrod://127.0.0.1
infinispan.client.hotrod.cache.closecache.near_cache.mode=INVALIDATED
infinispan.client.hotrod.cache.closecache.near_cache.max_entries=10000
infinispan.client.hotrod.cache.txcache.transaction.transaction_mode=NON_XAAutomatic cache creation
A neat feature that has been implemented as part of per-cache configuration, is the ability to automatically create a cache on the server on first use, if it is missing, by supplying either an existing template or a full-blown configuration.
ConfigurationBuilder builder = new ConfigurationBuilder()
.uri("hotrod://127.0.0.1");
.remoteCache("mydistcache")
.templateName("org.infinispan.DIST_SYNC");
RemoteCacheManager manager = new RemoteCacheManager(builder.build());
Cache<String, String> cache = manager.getCache("mydistcache");
...The above example using a properties file would look like:
infinispan.client.hotrod.uri=hotrod://127.0.0.1
infinispan.client.hotrod.cache.mydistcache.template=org.infinispan.DIST_SYNCGet it, Use it, Ask us!
